I am impressed by what I have seen in Amazon so far. it is very efficient and well managed. The sense of ownership and customer focus is so strong that you can feel it from employees in all levels. You have opportunity to work with bunch of smart people. People here are kind and willing to offer help as long as you ask.

Cons

The ramp up curve is big. It usually takes about few months to understand Amazon technology and culture. No formal training program.

Advice to Management

It is a challenge to grow so fast but still keep the original culture. Middle layer management team is the key.
